Viktor Hamburger (1900-2001)
Viktor Hamburger [5] was an embryologist who focused on neural development [6]. His scientific career stretched from the early 1920s as a student of Hans Spemann [7] to the late 1980s at Washington University [8] resolving the role of nerve growth factor [9] in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he...
متن کاملViktor Hamburger (1900–2001) Journey of a Neuroembryologist to the End of the Millennium and Beyond
But will there be anyone to remember us in another thousand years? Surely it's not possible that not a single molecule of memory will be found for us, like a yellowing manuscript at the bottom of a forgotten drawer, whose very cataloguing guarantees its eternity even if not a single reader ever discovers it. But will the catalog itself survive?
متن کامل"A Series of Normal Stages in the Development of the Chick Embryo" (1951), by Viktor Hamburger and Howard L. Hamilton
The developmental stages [4] of the chick [5] embryo were examined by Viktor Hamburger [6] and Howard L. Hamilton [7] in ?A Series of Normal Stages in the Development of the Chick Embryo,? published in the Journal of Morphology [8] in 1951. These stages were published to standardize the development of the chick [5] based on varying laboratory conditions and genetic differences. The stages Hambu...
متن کاملHamburger polyomaviruses
Epidemiological studies have suggested that consumption of beef may correlate with an increased risk of colorectal cancer. One hypothesis to explain this proposed link might be the presence of a carcinogenic infectious agent capable of withstanding cooking. Polyomaviruses are a ubiquitous family of thermostable non-enveloped DNA viruses that are known to be carcinogenic. Using virion enrichment...
متن کاملThe hamburger theorem
We generalize the ham sandwich theorem to d+1 measures in R as follows. Let μ1, μ2, . . . , μd+1 be absolutely continuous finite Borel measures on R. Let ωi = μi(R ) for i ∈ [d + 1], ω = min{ωi; i ∈ [d + 1]} and assume that ∑d+1 j=1 ωj = 1. Assume that ωi ≤ 1/d for every i ∈ [d + 1]. Then there exists a hyperplane h such that each open halfspace H defined by h satisfies μi(H) ≤ ( ∑d+1 j=1 μj(H)...
